Title: Improvements in and relating to electric switches and plug and socket connections
IPC: H01R13/707
Filed: 1938-11-02
Abstract: 522,147. Two-part couplings combined with switches. PARSONS, Ltd., C. H., and HANDLEY, G. B. Nov. 2, 1938, No. 31660. [Class 38 (i)] In a combined wall socket and switch having means operated by a pivotal arm in the earthing socket to lock the switch open while the plug is not in the socket, the same member that locks the switch also operates a pin-gripping pawl to lock the plug in the socket when the switch is closed. The locking member w is supported on a stud 12 on which it can slide and turn, and has an extension 10 that obstructs the movement of a slide 14 forming part of the switch-operating mechanism. When the plug is inserted the earthing pin pushes aside a cam o that rocks a lever r carrying a stud x which slides the member w away from the switch. A projection 15 on the member w is still in line with the slide 14 which, in closing of the switch, rocks the member v, the slot y being curved about the stud 12 as a centre, and the end z of the member w is moved away from the earthing socket, releasing a pawl which is rocked by a spring k into engagement with the earthing-pin p, Fig. 5. A spring serves to restore the lever r and member w to normal position when the plug is withdrawn. Specifications 487,224 and 487,225 are referred to.

Abstract: 1,273,006. Wrapping up coins; feeding webs. KOKUEI KIKAI SEISAKUSHO K.K. 24 June, 1969, No. 31809/69. Headings B8C and B8R. In a device for supplying wrapping paper to a coin-packing machine, a plurality of wrapping- paper rolls 4 are supported such that, on closing a rotary switch contact (27), (Fig. 3, not shown) with a selected contact (27a) of a set of switches 21, selected according to the size &c. of the coin to be packed, the rolls-support moves automatically to present the appropriate roll 4 to the packing machine. The rolls-support may be a reciprocable member or, as shown, a plate 3 rotatable about the axis of a shaft 2, and having holders 5 for the rolls. On closing the switch contact (27), a solenoid or electromagnet 26 retracts a locking bar 25 from a hole 24 in the plate to unlock the plate, and a motor 18 rotates the plate 3 and its shaft 2. The shaft 2 has a cam 20 provided with switch actuating portions 23. During rotation of the plate, an appropriate actuating portion 23 actuates a corresponding switch 21 to open it so that the motor 18, and hence the plate 3, stops and the solenoid 26 is de-energized to push the bar 25 back to its upper position to be inserted in another hole 24 to lock the plate in such a position that the appropriate roll is now presented to the packing machine. The wrapping paper is supplied to the packing machine by a roller mechanism (one such mechanism for each roll of paper) comprising a pair of rollers 6, 7, the roller 6 of which is driven on engagement of its clutch member 9 with a clutch member 10 rotated by a motor 16. A knife 17 severs appropriate lengths of the wrapping paper. The switches 21 may be provided with pilot lamps to give visual indication of the closed switch. In another embodiment (Fig. 4, not shown), the cam portions 23 may be replaced by projections e.g. screw heads (23a) provided on the underside of the plate 3 to actuate the switches 21 during the rotation of the disc.

Title: Improvements in or relating to the surface carburisation of steel
IPC: C23C8/22
Filed: 1945-11-26
Abstract: A method of surface carburizing steel or iron by heating in a carburizing atmosphere consists in passing a stream of mixed steam and air through or over a bed of charcoal maintained, out of contact with air other than that contained in the said stream, at a substantially constant temperature exceeding 800 DEG C., and preferably between 850 DEG C. and 1050 DEG C., the proportions of steam and air present in the stream and the rate of flow thereof being such that a substantial part, or the whole, of the heat arises from the combustion of the air and charcoal, and such that the carburizing gas thus produced is substantially dry.  The nitrogen content of the gas should be less than one half, e.g., a mixture of 75 per cent air and 25 per cent steam giving 43 per cent nitrogen in the gas, is mentioned as suitable.  Hydrocarbons, e.g., propane or butane, may be added to the gas which may be produced in the apparatus described in Specification 579,742.

Title: Improvements in or relating to magneto-strictive vibrators
IPC: H04R15/00
Filed: 1938-11-04
Abstract: 520,516. Magneto-strictive vibrators. ELECTRICAL RESEARCH PRODUCTS, Inc. Nov. 4, 1938, No. 31961. Convention date, Nov. 11, 1937. [Class 40 (iv)] [Also in Group XL] In a magneto-strictive device the vibrating member forms a closed low-reluctance path for the flux threading the coil or coils and is supported at its nodes for efficient vibration in a particular mode. This member may be laminated and may also be polarised by permanent magnets or by passing D.C. through the coils. In one embodiment, Fig. 10, the vibrating member is in the form of a closed rectangle with low reluctance ends 93 and supported at the centre points of its longer sides 91 by supports 92, 97 and 99, these being adjusted to cause no stress tending to deform the rectangle. Coils 96 are positioned concentrically with the magneto-strictive sides 81 and have sufficient clearance to avoid interfering with the longitudinal vibration. The vibrating member may be composed of rectangular laminations stamped out in one piece and be polarised by permanent magnets 94. To extend the frequency range, the elements 81 may be shaped to have their greatest thickness at the point of support and taper towards their ends. In another embodiment, Fig. 3, two concentric cylinders 36, 38, having low magnetic reluctance, are joined together at their ends by low-reluctance discs 37 and enclose between them the coil 39. The cylinders are supported separately and the coil allows them to vibrate longitudinally. They are polarised by a magnet 43. Another embodiment, Fig. 5, comprises two L-shaped vibrating elements 63 of magnetostrictive bimetallic construction with ends joined by low-reluctance material 62, polarized by magnet 61 and thus arranged to vibrate laterally, the lateral movement occurring at the apex 67. The coils 64 are connected in series aiding. Fig. 8 shows a further embodiment adapted for use in a submarine sound radiator. A toroidal core 71 carrying a winding 72 is embedded in a disc of insulating material 73 having a resilience comparable with that of the core and provided with a centrally located support 74. The core vibrates radially, the support 74 being at a node and energy from the core's periphery arrives at the orifice of the horn 77 in phase by equal paths 78 to transmit sound from the horn. A final embodiment, Fig. 11, comprises an elongated oval element 107 supported at its nodes 109. This element is of bimetallic construction and vibrates laterally. It is energized by coil 111 and polarized by magnets 106, the degree of polarization being adjustable. This arrangement may be adapted to convert mechanical energy into electrical energy. Specification 375,375 is referred to.

Abstract: 780,203. Feeding workpieces to presses. EVANS, F. A. Nov. 14, 1955 [Nov. 12, 1954], No. 32773/54. Addition to 733,347. Class 83 (4). A feed mechanism of the kind claimed in the parent Specification has means controlled by the press crankshaft for stopping the feed mechanism if the crankshaft overruns after the press has made one complete stroke and preferably also if the crankshaft is not set in motion in synchronism with the feed. The feed mechanism is driven from an electric motor through a pulley 10 and clutch 12 on the input side of a gearbox 11 whose output shaft carries a disc 32 connected to the feed mechanism. The clutch is operated by a fork 13 connected to a hand lever 16 pivoted at 14 and biased to the disengaged position by a spring 17. The hand lever works in a vertical slot in a frame 19 and is retained in its engaged position by a spring-biased collar 21 whose spigot end 20 engages in an enlargement at the lower end of the slot. A cranked lever 23 is pivoted at 24 to a link 25 secured to a spindle 26 which is also connected through a crank to a rod 27 slidable in frame 19 and having a finger 28 engaging in a groove in collar 21. The lever 23 is connected to a fluid pressure motor 36 which is energized by a valve operated by a cam on the press crankshaft immediately the latter commences to rotate whereby the lever 23 is moved out of the path of a peg 31 on the disc 32 and the feed mechanism continues to operate. If, however, the press crankshaft does not start at the correct moment, the motor 36 is not energized and the lever 23 is raised by engagement with the pin 31 whereby the lever 27 is moved to the left to withdraw spigot 20 from the frame 15 and permit spring 17 to disengage the clutch and stop the feed. The disc 32 also carries teeth 37 which normally pass the lever 23 without engagement. If, however, the press overruns or repeats, the motor 36 is re-energized and moves the lever 23 to the right whereby the lug 39 is engaged by the teeth 37 to raise the lever and hence disengage the feed clutch 12. In a modification (not shown) the peg 31 co-operates with a switch or switches controlling the feed driving motor.
